AUTOMQBILE SIGNAL.

" -Apuncmon nea Haren s1, 1923. serial No. 629,143.

A conduit 9 at the bottom of the frame l To all whometfmay concern.:

Be it known that I, CARL HOFFMAN, a c1t1, zen of the United States, andresident of the city of Allentown, county of Leh1gh, and State of Pennsylvania, have invented new and useful Im rovements in @automobile Signals, of whic the following 1s a specification. e

, My invention relates to annunciators, such as are carried by automobiles, indicating traiiic conditions and the obJect of my 1n-l vention is to provide a simple and highly eicient signal of this class which 1s readily actuated through circuits controlled by it switches, preferably located on the steering wheel of the automobile, the signal elements being compactly arranged within a single housm which is mounted on the rear left fender o the vehicle.

In the drawings: Fig. 1 is a view in side elevation of a touring car equipped with \my annunciator. Fig. 2 is an enlarged view of the signal box or frame, with one of the face platesre moved to show the interior` arrangement.

Fig. 3 is a view in side elevation of the Si al box or frame,and

ig. 4 is a vertical sectional view thereof. Fig. 5 is a cross sectional view on line so 5`5 of Fig. 2.

Fig. 6 is a cuits.

The signal boxis preferably supported by a hollow spindle 1 on the rear fender of.

as the vehicle and includes a rectangular frame 2 spacing front and rear transparent plates 3 and 4, respectively, upon which are printed the words Stop, Right and Left, in 'the order named from top to bottom. These ce words are preferablyprinted in red upon a white ground, so as to produce the most edective display.' `The frame. 2 has horizontally` disposed partitions 5 separating the interior ofthe e5 frame into Vthree compartments, one 'for each of thenoted trac directions.4 The sur faees'ot these partitions. are highly polished nto aid in reflecting the light of electric lampsv 6, two of which are located irl-each lof the e0 compartments, the vsockets 7 beingpro'ected through openings in the'sides of vthe. ame. 4These sockets 7 are supported 'b channeled members 8 which are secure to the sides of the frame 2, this channeled formaes tion providing a means by which the wiring is carried to the lamp `sockets.

diagram of the controlling cir-v tions, a cap piece carried by sai 2 forms part of the spindle 1 and communicates with the channeled members 8. l

A cap piece 10 serves to hold at the top angular moldings 12 which bind the plates 3 and 4 to the frame 2, these moldings being fastened to the frame at the sides by y screws 13.

-purpose of making the compartments light tight, I place a strip of rubber 14 between such partitions 5 and the plates 3 and 4. The operation of my improved annunciator will be readily apparent `from the diagrammatic showing in Fig. 6, wherein the source of electric energy is indicated at 20, leads to the stop compartment being shown at 21, with a control button 22 on the steering wheel; leads to the right compartment at 23 with control button 24; and leads to the left compartment at 25, with control button 26.

l claim as my invention:

1. An annunciator for motor vehicles including a frame with openings in the frontA ved to carry wires for supplyingr current to said lamps.

2. n annunciator for motor vehicles including a frame with openings in the front and rear, horizontally disposed spaced apart partitions forming compartments in said frame, such parttlons being provided .with

redecting surfaces,.transparent plates adaptf ed to close the openings of said frame and -upon which trame signals are indicated,

moldin for securing said plates in position, means or preventing rattling between said plates and said horizontally dis osed partframe and adapted to impart and engage said moldings to hold them mposition, a channeled .memx ber attached Vto each side of said frame, lamp Sockets carried vby said members and respec- 5 tively disposed in the compartments formed by said partitions, a conduit 'communicating with said channeled member, a spindle forming a continuation of said conduit for specification.

supporting said frame on a .part of the motor vehicle, said channeled members, con- 10 duit, and spindle-beingadapted to carry wires for supplying current to. said lamas.

In testimony whereof I have signed t is f CARL
